Do traditional festivals have the value of reservation?

Why should we keep traditional festivals? This is the best proof that our nation exists in this world and has a long history. Abandon these festivals, and some people will ask, what are the characteristics of your nation? What evidence does your country have to prove that it existed? What's your answer?

A nation does not have its own national characteristics, festivals and self-confidence. What is the need for existence? Since there is no need to exist, why not be slaughtered until it dies? Personally, no nationality means no ancestors and no descendants. When they were alive, their bones were different. When they died, they disappeared completely and no one remembered them.
